Other items used were a Johnson Controls A419 temperature control for controlling the cooling fans and Linear Actuators from Firgelli Automations in Seattle, WA. to open and close the vents. A Renai 7 stage heater, a cheap thermostat controlled window fan from Home Depot for air circulation, two duct booster fans for bringing in extra cool air from the outside (controlled with the vents by the A419). Three Toro ECXtra sprinkler controllers controlling 4 rainbird sprinkler valves for very fine control of the 4 drip watering zones including overhead misting. No artificial lighting has been needed as of yet and after our first winter, it doesn't look like we'll need them with the amount of sun we have year round.
